Workings of Ancient Calculating Device Deciphered

palegray.net writes "Scientists have discovered new meaning behind the functions of the Antikythera Mechanism, which has been referred to as the oldest known analog computing device. In addition to providing a means to calculate the dates for solar eclipses, the device apparently tracked the four-year cycles of the Olympiad. From the New York Times article: 'Only now, applying high-resolution imaging systems and three-dimensional X-ray tomography, have experts been able to decipher inscriptions and reconstruct functions of the bronze gears on the mechanism. The latest research has revealed details of dials on the instrument's back side, including the names of all 12 months of an ancient calendar.'"

      From her site,

      This model of the Antikythera Mechanism is made after schematic fig. 5 in Nature vol. 444 and includes a Hipparchos Solar Mechanism of my own design. However I see a-1 as an output to drive a hypothetical planetarium as illustrated.

      The Antikythera Mechanism cannot easily be driven from a-1 as any engineer will understand, taking into account the gear ratios. My input is the disk containing the lunar phase mechanism. This works beautifully and allows very subtle setting even with the additional load of my hypothetical planetarium.

      From the engineers point of view d-2 would be the perfect input gear. With a crown gear exactly like a-1 engaging d-2 and a little crank, the Antikythera Mechanism (and planetarium) can be driven smoothly and subtly. Experiments confirm this. There is however as far as I know no sign of this arrangement in the original, it is purely my personal curiosity that made me investigate this.

      My geocentric planetarium is based on modern data of planetary motion and is realised by conventional asymmetrical spur gear differentials as described in engineering text books. It is similar in principle to Mr. Wright's but rather different in details. I do not know of any detailed description of Mr. Wright's excellent work so I worked this out myself. As it represents the same solar mechanism, with good approximations, the differences cannot be great. Mine has 28 gears.

      The strange ratio of a-1/b-1 48/223 is an advantage here. My planetarium, after independent use, can be resynchronised with the Antikythera Mechanism from anywhere in a very wide window of time. Since a-1/b-1 is mirrored in my planetarium to provide a one-year-wheel there the actual ratio is irrelevant. I made b-1 with 223 teeth because I had to make it anyway for e-3 and the information does not exclude this.

      Second point: Galileo provided the observational evidence to support Copernicus, but this isn't what got him in trouble.

      What got Galileo in trouble is that he took his scientific ideas (including the wacky ones that no one ever hears about, like the tides being caused by the slowing down and speeding up of the earth's rotation every day) and was drawing theological conclusions from them. To talk about the earth going around the sun as a philosophical point was something the Church could live with (hence the good relations Copernicus enjoined). For an untrained layman to persist in making theological claims, however, is quite something else in the Church's mind (see Brodrick's biography of Galileo for more details concerning the theological controversy). Most of you get a up in arms when creationists insist that the earth is only 6000 years old, because that's an imposition of religion on to science, why shouldn't the Church get upset when scientists try to tell it about God?

For example, his book "Dialogue Concerning the Two Chief World Systems" one of the three literary figures parrots the words of Pope Urban VIII. Because Urban was an Aristotlean, Galileo named his character "Simplicius"; understandably, the Pope was not impressed. This did not improve his standing in the eyes of the powers that be.

  19. Computer Model Proves GeoCentrism by HighOrbit · · Score: 2, Interesting
    This is mostly a repost of some things I wrote a few years back, but this should serve as a cautionary tale about computer models and science. This device could "scientifically" prove geo-centrism in the sense of being valid science according to the scientific method.

    Valid reproducable observations that lead to a hypothesis and valid proven predictions does not make it "true". Based upon the Article, the Greeks used this to *accurately* predict the positions of planets. This meets all four steps of our modern scientific method.

    1. Observation and description of a phenomenon or group of phenomena. The Greeks see the planets, moon, and sun move across the sky
    2. Formulation of an hypothesis to explain the phenomena. The Greeks form a geo-centric hypothosis "in which each body describes a circle (the epicycle) around a point that itself moves in a circle around the earth"
    3. Use of the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations. The Greeks build a mental model of the universe to predict where the the heavenly bodies will be in the sky and then build a device (computer model) that will execute their prediction.
    4. Performance of experimental tests of the predictions by several independent experimenters and properly performed experiments. The Greeks can run the machine over and over and every time come up with a reasonably accurate prediction that can be verified by going back and seeing that the phenomena conforms to the prediction of the computer model

    So, does this mean that a geocentric universe was "proven" by science in the 1st century BC? We would say that was absurd because we have more information about the universe now than the Greeks had from just looking skyward. But how many other computer models and predictions do we take on faith as "science" which are based on incomplete information. Our best global warming climate models are extemely *inaccurate* compared to this relatively accurate device. Yet we accept the (modern) inaccurate models on faith and reject the (ancient) accurate model that this device "proves".

    So my point here is that "scientific" computer models should be greeted with skepticism, even when they accurately predict. They should be absolutely scorned when they fail to accurately predict. There are a whole bunch of "scientists" out there running computer similations that are far less predictive than this device that is likey based on a geocentric theory of the universe.

      ALL models should be greeted with skepticism. Hell, all THEORIES and all HYPOTHESES should be greeted with skepticism.

      That is the very foundation of successful application of the scientific method.

      There's a big problem with what you're saying, however... you say that a model that does not accurately predict should be scorned. That is false. Models are often revised to account for inaccurate predictions. As one famous scientist explained, it is not the Eureka! moments that drive true discovery, it is the "That's funny..." moments. In other words, the failure of a model to accuately predict will often lead to greater understanding of what is being modeled. Do you think that the General Theory of Relativity should be scorned, even though, as a modeal, it fails to accurately predict the existence of dark energy and dark matter?

      So, to sum up -- yes, skepticism is important in all science. But a model that does not predict accurately may still have value to the scientific community... at the very least, it can be the starting point for a revised model that does accurately predict.

      No, we don't. You ever open up the IPCC report and see the big error bars? Everyone knows that modern climate models come with substantial uncertainty. All models have uncertainty, some more and some less. The point with climate models is that, even with large error bars, you can still exclude hypotheses such as "the warming is mostly natural" or "the warming in 2100 will be less than 1 degree under business-as-usual emissions scenarios".

      and reject the (ancient) accurate model that this device "proves"

      Regardless of how accurate ancient models are, modern models are more accurate still, which is why we reject them in favor of newer models. This is the same as why we reject older climate models (e.g., simple energy balance models) in favor of modern general circulation models. No, they're not as accurate as even old theories of orbital mechanics; orbits are simple and predictable. That doesn't mean that they're not useful, or not scientific, or have no predictive skill.

      There are a whole bunch of "scientists" out there running computer similations that are far less predictive than this device that is likey based on a geocentric theory of the universe.

    The original Roman calendar had ten months, yes, and actually only covered about 300 days, with most of winter considered off-calendar. However, by tradition, the second Roman king, Numa Pompilius reformed this calendar and added January and February (at the end of the calendar), giving the year 12 months (and so at this time, the names of December, etc. as numbered months still made sense). This was the calendar used (with modifications) from roughly 700 BC to the introduction of the Julian calendar in 46BC. The calendar of Numa Pompilius ended up with some crazy leaps and intercalations to keep it reasonably in line with the solar year, so reform was definitely due.

    In doing so, the Romans consulted with Greek astronomers, who had a lot of data about such things (though the Julian calendar is merely a solar calendar that keeps pretty good time with the moon, and not a true lunisolar calendar like one based on the Metonic cycle would be). Greece at the time of the Antikythera mechanism (about 50-100 years earlier than the Julian reform), had in fact just come under Roman control.

    In addition to reforming the "leap" system, January got pushed to the start of the year, making the "number-names" months no longer descriptive, and the months of Quintilis and Sextilis were renamed for Julius Caesar and Augustus Caesar, respectively.

    The didn't exactly LIKE one another but they intermarried and got along. Alexander the Great (or rather more to the point, his father Phillip the Great) was Macedonian and would come to rule pretty much all the Greek Islands and (by the end of Alexander's life) most the known ancient world all the way to India.

    There is clear references in Alexander's diary that he suffered some discrimination as a child for being a Macedonian but it was like the difference between a modern-day Scottish and Welsh. Very much like that actually. Ultimately the political differences were small and the cultural differences even smaller. Small enough for Macedonians to become the first Greek emperors anyway.
    Now as for Macedonians having been Slavic - that is a bit of a stretch, the slavic nations as we typically think of them didn't really come into their own for close on a thousand years AFTER the time of Alexander, though they outlasted the Romans by a bit they appeared around the same time.
    I would say it's plausable that the Slavics may have had Macedonian ancestry, since Macedonia was quite possibly the first settlement of any kind of civilization in Europe but that far back we have almost no evidence of anything and that is pure conjecture. The Slavics could just as easily have been there 10 thousand years earlier and just not left any earlier evidence. To say they may be descended from Macedonians is plausable, but no more so than to say they may have been the descendents of interbreeding between early homo-sapiens and early homo-Neanderthalenses that only developed into a more structured society later. Their highly barbarian society (as opposed to the highly tribal Greeks and Macedonians) doesn't really fit with a RECENT common descent though (for what my gutt feeling is worth - which is at least as much as any other person who studied ancient cultural history).

    In the end, the only thing we know for an absolute fact about descent more than one thousand years old is that we are probably ALL descended from Africans our earliest human ancestors were probably dark skinned. Even THEN there are things we do not know - like did the Australian Aborigines split off from the same people who migrated to Europe ? Or did they reach Australia before the continents split ?
    There is no way to know short of DNA research which nobody has done yet.

    *No, the fact that it is written down is NOT proof to a historian. Alexander probably wouldn't lie about being Macedonian as it must have put a crimp on his career prospects, but we cannot know that he DIDN'T - and a king could easilly pretty damn sure that nothing ever gets written down that contradicts his story - so seriously, we have no real proof. Only tiny bits of supporting evidence, history is trying to figure out the most sensible explanations for them, knowing one of your students will probably come up with something better than you did and be too lazy to write in his paper.

    1. The early Franks were pretty proud that they're warriors, not scribes. They're not the only ones.

    Charlemagne was the first monarch there who even tried to learn to write. Very late in life and, while he must be commended for his real efforts and time dedicated, it seems to have gone nowhere.

    2. Antiquity itself wasn't that much more literate. Yes, in the middle ages only the rich learned to read and write. Guess what? The Hellots of Sparta and the poor of Rome, but especially _outside_ Rome weren't much richer and nobody taught them to read and write. And even in Egypt, while for the rich it was a thing of _pride_ to be literate (and addressing a letter "to your scribe" was a form of flattery, meaning, "I know you're your own scribe"), don't think that the poor working the fields had time to go to school.

    We have a somewhat distorted view of Greece and Rome, in that basically we have a distorted tunnel view of it. We see the greatness of Athens at its peak, or Sparta... which were populated only with rich slave owners, whose only job was to be soldiers and philosophers. Athens additionally had managed to cheat the other Greek states, who had joined as _allies_ against Persia, with Athens as merely heading and organizing the army and funds, but found themselves actually turned into vassals of Athens and paying tribute as... well, more like a form of paying for protection. And not against the Persians, if you know what I mean.

    So, yeah, the Athenians of Pericle could build great statues and temples, and sit around debating politics and philosophy, on the money of the whole rest of Greece and on the work of countless slaves. They _were_ the rich guys, and yeah, they could read and write. Big improvement over the Dark Ages, where also the rich guys could read and write, eh?

    Ditto in Rome. We look mainly at what happened inside Rome itself, and the great democracy they had, but forget about the whole regions where they reduced the peasants to utter poverty by confiscating the lands and distributing the lands of a whole bloody province to half a dozen rich families. Again, we see the rich and maybe also middle classes this time, getting an education and living in nice cities. And a few slaves used as personal clerks. But forget about the 80% of the population, who was working the fields outside the cities, and who lived a heck of a lot worse and nobody educated those. Don't think that anyone educated the slaves in Sicily, which are documented to have been borderline starved and sometimes outright starved, so their masters could sell more grain to Rome. Or don't think that the slaves in the mines, which was little more than a slow death sentence, got educated first.

    Ancient times were a lot shittier than some people assume. Maybe a little better than the darkest of the Dark Ages, but for most of the poor people, not by much or not at all.

    3. Romans insisted on your learning Roman or Greek too, so...

    4. What we inherited as the idea of the Dark Ages is, well, partially (though not totally) just the eternal circle of nihilism. Each time people go disillusioned, it seems to be a common reaction to go basically "OMG, our contemporary culture is nothing, we're living in the (new) Dark Ages" and "somewhere else / somewhere in the past, now that was Teh Golden Age, and the land of milk and honey!"

    So back then, someone thought Rome was all that. Funnily enough, Rome at various points had thought Greece had been all that. And Greece had thought that their Mycaenean ancestors had been all that. And if you go forward in time instead, you find a disillusioned 19'th century England thinking that the middle ages had been such a golden age of chivalry. Some still do.
